'8 Claims. (01. 139-485) sponding side of the shuttle with a closesurface contact fit. This causes uneven wear of the shuttle, binder andbox parts and impairs shuttle checking action as the shuttle is beingboxed.

If a resilient pivot mounting is provided for the binder, the binder maybe displaced radially towards the axis of the pivot and this may causethe shuttle to be boxed out of alignment with the corresponding picker.Moreover, the lateral displacement of the binder permitted by such aresilient pivot mounting may affect adversely the accuracy andsensitivity of the protectionmotion.

One object of the present invention is to provide a new and improvedpivot mounting for the binder, which permits the binder to tilt aboutits longitudinal axis to maintain continuous frictional surface contactbetween the binder and the shuttle as it is being boxed and which is notyieldable in a radial direction with respect to the axis of the pivotmounting, so that axial alignand from an inspection of "the accompanyingv drawings, in which: v

Fig. l is top plan View of a lay and shuttle box assembly shown at theinstant the shuttle is being boxed;

Fig. 2 is a transverse section of the lay and shuttle box assemblytaken, on lines 2-2 of Fig. 1 and shown with the shuttle coming in ateven keel; and

Fig. 3 is a transverse section of the lay and shuttle box assemblysimilar to that of Fig. 2 but showing the shuttle coming in slightlytipped about its longitudinal axis.

Referring to the drawings, the binder post mounting of the presentinvention is shown applied to a shuttle box In fastened to the lay I l,as for example, by bolts l2, and comprising a bottom plate I3, a frontplate It with a top shuttle guide plate l5 secured thereto, and a rearorback plate l6 spaced from said front plate to receive the 2conventional shuttle shuttle boxing action.

The shuttle H is propelled by a picker stick IS in any suitable manner.The bottom.box plate [3 has a slot 2!] for the passage of the pickerstick L8.

The invention is not limited to' any-particular kind of pickingmechanism or general shuttle box construction and that shown is forillustrative purposes .only.

The rear of the shuttle box H] has extending therealong a shuttle binder25 pivotedat one end H therebetween during 2% to the bottom box plate 13by a pivot mounting 21'and engaging at its other free end the usualprotector finger (not shown) for protector motion control. A spring (notshown) yieldingly 'holds the binder 25 inwardly towards the front boxplate M to check the shuttle Ii as it moves into the box In.

.The binder 25 comprises anelongated bar 28 desirably of wood anddesirably provided on its inner shuttle contacting side with a lining3!] of leather or similar flexible cushioning material cemented orotherwise secured thereto. At its pivoted end 26, the binder'25 has ahub 3| forming part of the pivot mounting 21, as will be described.

The binder pivot mounting 27 comprises a rigid.

pivot pin 32, desirably of metal, secured to the bottom box plate l3 byaclamping bolt or stud ably ofmeta1 or other suitable bearing material,

lining the inside of the binder hub 3i and having rotative bearingengagement with the outer periphery of the pivot pin 32. The hub bushing34 has a hole 35 presenting an inner convexly curved surface 36 inrocking engagement with the pivot pin 32, permitting said bushing 34 notonly to rotate about the pivot axis of the binder mounting 21 but totilt about an axis transverse to said pivot axis, as will be more fullydescribed.

More specifically, the pivot pin 32 is an eccentric bushing designed topermit adjustments in the transverse position of the pivot axis of thebinder mounting 21. The eccentric bushing has a cylindrical bearingshank 38 and an annular base flange 4U seated on the bottom box plate l3and provided With a series of holes or sockets 4| around its peripheryto receive a suitable wrench or other turning tool. The binder hubbushing 34 seats on the base flange 40 and engages the Normally, thebolt 33 is tightened to lock the eccentric bushing 32 in adjustedposition against rotation. When it is desired to adjust the transverseposition of the center axis of the bushing 32, the bolt head 36 isturned to turn the bolt 33 in the splined nut 45 and to loosen therebythe eccentric bushing 32. The bushing 32 can then be turned by insertinga wrench into a socket 41 of its base flange 4B and rotating therebysaid bushing into the desired position. When the proper adjustment inthe rotative position of the eccentric bushing 32 has been made, thebolt 33 may be turned to lock the parts in adjusted position.

The hole 35 of the hub bushing 34 tapers from opposite ends towardssubstantially the center to present the smooth rounded internal surface36 convexly curved lengthwise of said bushing. The surface is curvedsubstantially circularly in the radial planes of the axis of the hubbushing 34, so that said hub bushing constitutes substantially a solidof revolution generated by a segment of a circle rotating about an axiswhich Y is spaced from said segment, which is substantially parallel tothe chord of said segment and which is located on the side of the are ofsaid segment opposite said chord. The radius of the arc is small enoughto permit tilting of the binder about its longitudinal axis through anangle sufficient to accommodate any keeling of the shuttle ll normallyencountered during shuttle boxing operations, but is large enough sothat the spur of the shuttle I! is maintained substantially in alignmentwith the corresponding icker.

In Fig. 2, the shuttle I! is shown coming into the box It at even keel.In this position, the inner leather lined surface of the binder 25 is inclose, continuous, frictional surface contact with the correspondingside; of the shuttle II. In Fig. 3, the shuttle i1 is shown coming intothe box It, slightly tilted about its longitudinal axis.

In this position, the binder 25, through the tilting compensatingmovement of its hub bushing 34 about the pivot bushing 32, has beentilted about its longitudinal axis in position corresponding to thetilted position of the shuttle I! and into close, continuous, frictionalsurface contact with the side of said shuttle. Even wear of the shuttlecontacting parts is thereby assured and effective shuttle checkingaction is by that means maintained at all times.

While the invention has been described with particular reference to aspecific embodiment, it is to be understood that it is not limitedtheretobut is to be construed broadly and strictly solely by the scopeof the appended claims.
